In the 19th year of the Republic of China, on a clear and windy night, there was an explosion and thousands of people went into exile. When I first arrived in Peking, my family said: study honestly and don't mess around. Xu Tingyan refused to participate in the protest. Later, when he arrived in Nanjing, his friends persuaded him that marrying a talented person is the right way to go, but Xu Tingyan scoffed. Later, when he moved westward, the country fell, his family was destroyed, and the people were in dire straits. Xu Tingyan recalled that morning many years ago and decided to devote himself to industry. Now that chaos has arisen, he has no choice but to fight to protect his hometown.
